What causes varicocele?

Although there is no clearly defined reason for varicocele, it is thought to be caused by the malfunction of the valves in the veins of the testicle. As a result of the malfunction of these valves, the veins enlarge, and the venous blood accumulates in and around the testicle, which may lead to poor sperm quality or count.

Due to the position of the left testicle vein, varicocele is generally seen on the left side. However, it is known that unilateral varicocele may disrupt sperm production in both testicles.

 

What is varicocele?

Testicles are a pair of reproductive organs located in a pouch of skin called the scrotum. And, varicocele is the name given to the enlargement of the veins of the testicles. Varicocele is similar to the varicose veins seen in legs.

It is one of the common reasons for low sperm production, poor sperm quality, and male infertility. Varicocele may also disrupt the development of the testicle and lead to testicular shrinkage. However, there is no rule that every varicocele will affect sperm production.

 

What are the symptoms of varicocele?

Varicocele generally does not show any symptoms. But, it may sometimes cause pain in the testicle.

The intensity of the varicocele pain increases with physical exercises and standing for long times. It tends to increase later in the day and decreases when you lie down and rest. Varicocele progresses and becomes evident in the scrotum over time.
